All kittens should be tested for these fatal diseases. These diseases can be transferred from the mother to the kittens and they can be acquired from contact with other cats. These diseases are present in our area and are always fatal. Kittens and cats affected FIV or FeLeuk usually look completely normal for months to years before they waste away and die. All new cats in a household should be tested before introducing them to other cats to prevent all your cats from catching these deadly diseases. If you choose to decline Feline Leukemia and Feline AIDS/FIV Testing, you may be investing a lot of money in a cat with a bleak future. Anesthesia and surgical procedures can also speed up the course of these diseases.
